How do you manage prostate cancer in patients that cannot swallow pills?
The only one suitable for feeding tube administration is apalutamide (must be 8 French or greater feeding tube size). My oncology pharmacist suggests tablet(s) can be placed in a syringe (whole, not crushed), distilled water then added, shaken vigorously to disperse contents, administered through...
How would you approach an isolated prostate recurrence of high-risk prostate cancer following definitive EBRT?
It is important to know: 1) time from cessation of hormones and time to recurrence. Better to also have T levels. 2) velocity of PSA rise. 3) absolute PSA value Longer disease free interval, slow PSA kinetics and low PSA suggests prostate only recurrences. I have also begun to incorporate Aximun s...
What time frame, number of PSAs, and calculator do you use for calculating PSA doubling times?
I typically use only values of 0.10 ng/mL or greater, and at least 3 separate PSA values that are at least 3 weeks apart from each other. The greater the number of PSA values, the more accurate the PSADT calculation will be. I like to use the MSKCC calculator: Prostate Cancer Nomograms: PSA Doubling...
Do you prefer kidney ultrasound or a non-contrast CT scan to evaluate for nephrolithiasis in an asymptomatic patient with primary hyperparathyroidism?
I first order an ultrasound due to the lack of concern for radiation exposure and if it is equivocal then follow-up with a CT scan. Ultrasound is not as sensitive as a CT scan especially for very small stones.
What is your approach to patients who insist on testosterone replacement therapy despite normal testosterone levels on repeated labs?
I explain that with a normal testosterone level there is no indication for testosterone replacement. Hormone replacement is always about evaluating risks and benefits. With a normal testosterone level the risks outweigh the benefit. I offer to evaluate causes for patient’s symptoms such as sleep apn...
What are your top takeaways in GU Cancers from ASCO 2025?
Here are the top 3 prostate cancer studies: AMPLITUDE. LBA5006: Attard and colleagues show that the PARP inhibitor niraparib plus abiraterone/prednisone delayed rPFS in men with mHSPC (HR 0.63, p = 0.0001), meaning this is the first ARPI/PARPI successful combination in this hormone-sensitive HRRm se...
Would you recommend initiation of cinacalcet in a patient with hypercalcemia and recurrent nephrolithiasis attributed to an atypical presentation of familial hypocalciuric hypercalcemia?
I would really like to know the level of the patient’s parathyroid hormone. If it is low, cinacalcet would probably not be helpful. Stephen B Erickson, MD
Do you recommend restricting alcohol use in patients with recurrent nephrolithiasis?
No. Clearly excess alcohol use is to be avoided. I much prefer water or citrate containing beverages for stone prevention. Beer has some oxalate content and is better avoided. Stephen B. Erickson, MD
Is switching to carboplatin/gemcitabine reasonable for a patient with muscle invasive bladder CA who proceeded to cystectomy first and had AKI with cisplatin/gemcitabine prohibiting further cisplatin?
There is not a role for gemcitabine and carboplatin in the adjuvant setting in patients with muscle invasive bladder cancer. Based on CheckMate 274 (Bajorin et al., PMID 34077643), in patients with MIBC with a high risk of recurrence (pT3, pT4a, or pN+ and not eligible for or declined adjuvant cispl...
How do you manage or monitor hypogonadal men on clomiphene citrate?
I typically monitor men being treated for hypogonadism on clomiphene citrate the same as other hypogonadal men. There is less concern for timing of ordering testosterone levels to assess response in regard to treatment administration. There is also theoretically less concern for abnormal hematocrit ...
